WHEEL FOR TRACTIQN-ENGINES.

Specification of Letters Patent.

Patented Jan. 23, 1906.

To all whom, it may concern.

Be it known that I, IRVIN O. HOTALING, a citizen of the United States, residing at Crab Orchard, in the county of Johnson and State of Nebraska, have invented certain new and useful Improvements in Wheels for Trac titan-Engines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to a wheel for traction-engines, and particularly to an improvement upon my prior patent, No.- 7 89,913.

The invention has for an object to provide means for positively holding spurs inprojecttion of a portion of a wheel, showing the invention applied thereto andl ig. 2 is a detail" perspective illustrating the application of the invention. 7

Like letters of reference refer to like parts in the several fi fires of the drawings.

The letter A esignates a wheel of any desired construction such as ordinarily used u on traction engines or similar vehicles. T 's wheel is provided with a series of spokes A and with the usual rim A upon which the supporting bracket B for the spurs C is mounted at its opposite ends by means of bolts or other fastenings B. This bracket is provided'upon its upper face with a series of apertures of greater diameter than the spurs to ermit their free passage therethrough, while each of the spurs is provided with a stop projection C to limit the upward travel thereof. The spurs are also formed at their ends beyond the bracket B with eyes C through which the operating-rod C is passed, said rod being pivoted at its end to a suitable lug 15*, carried at one end of the bracket B. The opposite end of the bar is formed with a .handle C and with a tooth C adapted to en- ..gage in the notches or recesses C of a ratchetplate C applied to the end of the bracket B.

The spurs are normally withdrawn Within the perip ery of the rim by means of a tensionspring D, which extends from the lever C to %ne of the spokes of the wheel, as shown in In the'operation of the invention the spurs are projected by pressure upon the handle of the operating-lever, which is then engaged with a rack-bar to holdthe spurs at any desired degree of projection and retain the spring under tension. As soon as the bar is released the spring immediately retracts the spurs, which being all carried by the bar are simultaneously moved. 7

This construction provides means by which the arts may be quickly and simply operated w enever found necessary for convenience and one which is not liable to be injured in the operation of the vehicle or to be clogged by the accumulation of dirt or dust thereon in the ordinary traffic conditions to which the vehicle or engine is submitted. Having thus fully described my invention and set forth its merits, what I claim as new, and desire to secure by Letters Patent, is 1. An attachment for wheels, comprising a bracket-plate adapted to be applied to the rim thereof, a series of spurs extending through said plate, and an operating-lever connected to each of said spurs andpivotally mounted upon said bracket;

2. .An attachment for wheels, comprising a bracket-plate adapted to be applied to the rim thereof, a series of spurs extending throu h said plate, an operating-lever connected to each of said s urs and pivotally mounted upon said bracl et, and a ratchetbar carried at the opposite end of the bracket from the pivot of said lever. 3. An attachment for wheels, comprising a bracket-plate adapted to be applied to the rim thereof, a series of spurs extending through said plate, an operating-lever con nected to each of said spurs and pivotally mountcdupon said bracket, a ratchet-bar carried at the opposite end of the bracket from the pivot of said lever, and a retracting spring extending'from said lever to a relatively fixed portion of the wheel.

4. An attachment for wheels, comprising an apertured supporting-bracket, a series of spurs extending therethrough' and through the .wheel, eyes at the inner ends of said spurs, an operating-lever extending through said eyes, a pivotal lug carried by the bracket at one end of said operating-lover, a ratchettooth carried by said lever; and a) cooperatin ratchet-plate at the opposite end of sai bracket.

5. An attachment for wheels, comprising an apertured supporting-bracket, a series of spurs extending therethrough and through the Wheel, eyes at the inner ends of said spurs, an opereting-lever extending through said eyes, a ivotal lug carried by the bracket at one en of said operating-lever, a ratchettooth carried by said lever, 11 cooperating ratchet-plate at the opposite end of said bracket, a stop projection carried by said spurs to engage the under face of said bracket, and a retracting-s ring extending from said 15 lever to a spoke 0 the wheel.

In testimony whereof I hereunto affix my signature in the presence of two witnesses.
